Found teen with red hoodie near Ponte Vecchio

I found a teen around 3:15 pm this afternoon near the Ponte Vecchio along the Arno in Florence. He's about 16, with short brown hair and olive skin, wearing a red hoodie under a black jacket, dark jeans, and bright blue sneakers, with a light gray backpack that has a yellow tag. He seemed anxious and kept asking for his family; we hung around the bridge entrance while I helped him connect to a nearby shop's Wi‑Fi to contact a relative until a guardian could arrive. Identifying features include a blue scarab ring on his right hand and a small star tattoo behind his left ear. If you recognize him or can help reunite him, please use the app to message this post so we can connect you with his guardians.
